I have personas and classic theme restorer installed so I can have the tabs not be on top, and a non moving squirrel picture
on the frame. I got the computer used last year, maybe the year before, It's been lightning fast, but I use it for business
social media stuff, 30 twitter pages open to monitor hashtag pages. while loading other pages I get script slow errors,

The computer gets HOT the fan is beginning to make noise because it always runs. Even if I open one ONE ebay page (in FF)
and let it sit there, it will within 20 seconds stop responding and get HOT. As I write this on safari the machine is running fine
fan at slow idle, room temp 82 Humid no A/C.

The computer was wiped, new OS NEW FF 39 new when I set up this machine. When using FF along with Safari or Photoshop
12 I think, they can all be on and working, but FF will freeze, the others will work, and the fan runs so fast it lifts the machine off the table.

I have read and tried so many of the message board fixes, including the about:config tell the flash player not to load in each page
repeatedly if not used, no help. I take a screen pic, and then restore it to original if it don't work.
Something about a plug-in container. Activity monitor also says FF uses more than 450MB ram Really….? Normal….? 1 tab…?
Well safari has 418 MB …..

Done some of the fix it's on the FF help pages, turned off plugins safe-mode still spins up the turbines.
Not installed a new FF as there does not seen to be a real fix in doing that from what I have read.

Had this machine for a while, use to work fine, lightning fast, no fan unless watching a movie, now I don't even
try using youtube…..

No other add-ons readers, tool bars etc. installed. Ever. I basically do the same thing all the time. Also
for some reason even though flash is always manually updated, videos even GIF's on twitter now
place an error in the center of the post "your browser does not support video playback"

How can the dam thing use more than 100% of the cpu resources anyway……? WTF ???? Using some of the
CPU from tomorrow ????? Some kind of payday loan FF has for the CPU ????

Load_payday_CPU_firefox_interest-rate_120%_ :true ??? Where is it ?

I can load other info if anyone gives me an idea where to get it terminal, activity monitor, air traffic control, what have you.

I have post this questions a week ago but there is no response of my questions. I re-post it and hope someone could help to resolve the problem.
The firefox v.65 crash , usually after 3o mins, when I have the new brought photoshop elements 2019 program running in the background. After crashed I try to restore the tab. However, firefox crash again right after restart and restore the tab. If I keep trying to restore the tab. The firefox has no response and freeze. A error message come out " video driver failed to restart ....... Sometime the computer get into blue screen and die. i find that the problem also happen with Microsoft Edge browser too. I google the possible issue of the crash and get some information regarding the crash. It may be cause by the photoshop element face detection feature use too much memory to run the program or the program has memory leak problem that cause firefox crash.

I did check my computer RAM memory and PC window system files. they did not show any error. I refresh firefox and reinstall my video driver. However, it make no change of the crash situation. The firefox crash and Blue screen die issues only happen if I run my photoshop element and premier 2019 program at the same time. Adobe support said that it was not photoshop element program problem for the firefox crash.

I want to find out what is the root problem of the crash and how to fix it. I also want to know any known issue firefox crash assoicated with photoshop elements program.

I launch Firefox and access the website. The destination website is simple, rich, regardless of type.
A few seconds after the website is displayed, the number of revolutions of the power supply fan increases and the sound of the fan increases. And although the temperature of the power supply unit does not change greatly, the rotational speed of the fan is nearly doubled. As soon as I close the Firefox window it starts to slow down.

I endure the noise of fans and use Firefox for 20-30 minutes continuously. At this time, even if the user does not operate it, the fan rotation speed maintains the high-speed range just by leaving the window open and leaving. As soon as the window is closed, the speed drops.

This doesn't happen with other web browsers. This happens even if I recreate the profile.

My Firefox is taking about a minute to load www.hl.co.uk. HL support have said that there is a problem with add ons and to "Refresh" Firefox. The page loads OK in Safe Mode and also loads OK immediately after a Refresh. However, the problem then comes back.

On going to hl.co.uk, the whole browser freezes (no other page will load) and the CPU goes to about 28% and stays there. After a minute the page loads and the CPU reverts to background %.

System is: Win 7 fully updated (except Win 10 updates); Firefox 38.8 ESR (FF45 breaks a lot of stuff as it defaults to 64 bit installation).
- I have tried other FF versions back and forward and no difference
- Addons are Avast Online security, Classic Theme Restorer, Classic Toobar Buttons, New Tab Homepage.
- Whilst safe mode disable of Addons works to cure the issue, disabling Addons manually does not help.
- The problem only occurs on the first load of www.hl.co.uk after starting Firefox. If you leave the page and go back to it, there is no delay - if you close FF and wait for it to fully exit then re-start, the problem occurs again - and again only once.
- Totally reproducible!
- IE11 loads the page fine,
- Firefox is not slow on any other page (other than occasional but totally usual delays).

Unfortunately HL have declined any further help and suggest usign another browser - but it is clear that many of their users have the same problem

I'm getting a strange jump in memory use by Firefox. I'm monitoring Firefox memory use with the add-on called "Memory Restart." I keep 13 pinned tabs on my browser (they always load at boot-up). Those 13 tabs take up around 140MB of RAM. I also tend to keep around 50-100 tabs in my browser (I used Session Manager). But when I boot up, none of those tabs open until I click on a specific tab. See screen shot -- this is how my Firefox session typically boots.

After all the pinned tabs load Memory Restart shows around 140MB in use. About 10 seconds later I get a "flash" on the screen with a yellow banner under the tab section that says "Firefox memory has increased by more than 669MB since last refresh interval" (see image). Something is causing Firefox RAM use to jump immediately from 140MB to 669MB about 10 seconds after all my pinned tabs load. What could be causing this immediate large chunk of RAM use, even though none of the non-pinned tabs have been selected. ???

Fan runs high & hot watching youtube videos. Have new macbook pro retina 15" mid 2015. 2.5 GHz intel core i7. Started happening after second to last Firefox update. Updated to most current thinking it would be fixed. It doesn't happen if I use Safari. Apple support senior lead tried to resolve issues. Sorry, I'm not very technical. Tried shift, control,option start. Tried option, command,R,P start. Tried logging on as a new user. Tried so many options, I can't remember them all. Uninstalled, reinstalled,and uninstalled again. ran disk repair(?). Followed Firefox troubleshoot all the way to the end. Started in Safe Mode...everything. She told me to contact Mozilla to see if you had any answers to my issues.
I also had issues last week with Firefox crashing 3-4 times in a row while watching youtube. I sent reports to Firefox.
I hope someone can help me. I prefer Firefox to Safari!
Thank you!

It didn't start until the last update. I'm on Mac Snow Leopard and I tried turning off extensions. I have nothing else open, no other software except utility (to confirm its FF sucking the RAM). I have 1 or 2 tabs open. And yet it's sucking over half my RAM! I don't normally need that much and therefore haven't bothered to upgrade. No way I should need to up the RAM JUST for a browser with no extensions on and only 1 or 2 tabs open! What is going on here?

Why Firefox using all of my memory.
My PC 8GB RAM.
Firefox uses 6GB RAM only for 1 tab?
I only read manga at http://www.mangahere.cc/
if the ram is almost full, I have to restart Firefox.
Why is RAM management in Firefox so bad?
I'm tired of this, please fix it.
If you don't believe it, you can test it by reading a random manga.

Why do I restart firefox when ram starts full.
Because, if I don't restart, then the other programs that run will lag or hang.
In other words, Firefox makes other programs to move to a virtual memory (page file).

Hello all!
For the past few weeks, Firefox seems to be a large CPU hog. It uses around 30-50% of the CPU for seemingly no reason. I have ADBlock off (As you can see) There are only two tabs open (I am running Opera as well) I've cleared the cache, I've refreshed the download of Firefox as well. Could someone give me any other suggestions?

By the way, my laptop is a Dell XPS 12 (2014) with an Intel Core i5 4200U and 4GB of RAM
Thanks!

A paranoid thought, but I'm looking for some feedback.

I'm aware Firefox is a memory hog and there's some kind of memory leak situation, but it can easily get up to 2.5 G of the "private working set" memory.

I recently noticed Firefox doesn't have a value for its "Image Path Name" in the windows task manager. Coupled with the high memory use, does this look at all suspicious?

The picture attached is a few minutes after Firefox was loaded. I have a session with about 60-70 tabs restored (the tabs themselves do not have the web pages loaded, its just visible in my tab bar with the name oft he site so when I click it, it will load the actual page).

The picture shows the memory at around 500mb - Sure, I have a lot of tabs, but is there really that much memory consumed by those tabs when they are functionally just bookmarks? This was a minute or two after Firefox was restarted.

The part that makes me feel paranoid is the path not showing up in task manager. Makes me think of some kind of trojan-horse type virus running off the process Firefox is identified on (if that makes sense?).

Somehow, with 18gb memory, Firefox can bog my system down after my computer's been running for a day. Am I expecting too much thinking it should stay "quick as a whip" for at least a few days?

I use Firefox on Windows and Firefox tries to use too much of my system's RAM. I know this is for performance reasons BUT there is very little performance gain. This behavior is fine for users who only run Firefox and little else. BUT I use other memory intensive apps not only Firefox so Firefox using up lots of my RAM is very bad for my use case.

On a system with lots of RAM when I use gmail and Facebook on Firefox the firefox processes can bloat to more than 2.5GB! And it actually seems to start getting slower at that point.

But if I run Firefox in a Windows Virtual Machine with only 1.5GB RAM and start using gmail and Facebook a lot the largest firefox process only gets to a max of 750MB. So that is proof that Firefox can actually work with less RAM without crashing.

How can I get Firefox to behave as if the system has less RAM (e.g. just set a max RAM limit) without to resorting to running it in a VM? I have tried stuff like Process Governor but Firefox tends to crash when it hits the limit instead of running the GC. In contrast on a virtual machine with less RAM Firefox doesn't seem to crash and just uses less RAM.

Is there also a way to get Firefox to automatically do what the about:memory "Minimize memory usage" button does, when it starts to go past a memory usage threshold?

I have been using Firefox for more than 10 years now. it is the best browser out there. However, starting from last year I have been noticing that my computer's fan is almost always working which takes too much of my battery and I figured that Firefox is the main issue (I did so many research and tests %100 sure). Later, I herd about the new Firefox quantum, and decided to wait and not switch to another browser. the new one was released and I installed it the very first day. I was super happy that it's much faster and use less memory than other browsers (that's right). However, lately (about a month) I noticed the same the fan is always working again, so I check the task manager and found my dear Firefox quantum acting up again even though 3 taps are opened.

I really need help with this issue to stay using Firefox, I am tired of this issue and really considering switching to another browser because this is just not good at all. and I could not find any way to fix it. please see the attached pic it's just unbelievable.

Would someone please help me with a constant crashing of my Firefox Browser 41.01.1? I recently loaded WIN, 7pro 32, which replaced XP. I've reset my browser but seems to be getting worse. I added a few of the most recent reports;

Hi all!

I've been experiencing this problem for quite some time (≈1.5 years) and have finally decided to speak up, since it seems like either the team hasn't solved this bug yet or no one else experiences this.

Every so often, while browsing, pages will stop loading and the error, "Server not found," appears. The trigger seems to be a high-ish amount of RAM use, about 1GB. This happens every couple days if I don't open too many tabs with high RAM use (e.g. YouTube, NYT, etc.) or every couple hours if I'm browsing heavily! Refreshing and/or clearing cache have no effect. Only restarting Firefox (starting RAM use is ≈350 MB) allows me to load pages again—annoying if I fill out a long form, click "Next", and have to start all over again because the next screen doesn't load. This issue frustrates enough that I've finally decided to give Chrome another go (gasp!) and surprisingly, no niggles yet.

I'm on the latest version of Firefox on Windows 7 Pro x64. Hardware: Intel Core i5-2500K, 12GB RAM, 128GB SSD, AMD ATI 5850 Series. Internet connection is perfect at 20Mbps and other browsers run well even when Firefox doesn't. I've tried un- and reinstalling, starting with a new profile (syncing only bookmarks), and even deleting my %appdata% folder to try anew. As you can see, it's quite frustrating and time-consuming!

I'd love to keep Firefox as my primary browser—its customizability and design are the main draws. Any help much appreciated!

I have a problem with high CPU usage only when watching videos. When I use I.E. 9 watching the same video, it will drop from about 100% usually to 56% (cook's country.com for example). I believe this is a browser problem. I use Firefox as a primary browser & would like to know what may be causing the high usage as the videos will not "work" as well as they should. I feel that if the CPU usage was a little lower, I would not have any problem viewing the videos as what it does is start & stop constantly, and that is very aggravating to me.

The browser crashes while loading a page when visiting sites.
Youtube and twitter sites on start-up and other sites when browsing through them,
even on the Mozilla help/support pages.
Tried all the solutions as suggested on the help-pages, de-installed Firefox, peformed new installation and a new profile. No improvement, still crashes.
One oddity in the crash report; "CPU Info-warning: family 20 model 2 stepping 0 ".
The crash-problem started a few weeks back, before it worked good for years.
No changes in the hardware or software are done on my behalf and everything is kept automatically up-to-date.
Any advice or direcions to a solution are really appreciated.
Thanks in advance,

I've been using FF for ~8 years and since I've moved on to Linux, I've also been checking out it's memory usage.

Why does it always happen that when FF starts, it takes around 300 MB of memory (no page opened), but after usage, when I close and open tabs, the usages increases ever after -- 400, 550, 600, 700..... till all my 8GB is consumed.

Don't blame addons and --safe-mode etc... I've tried all those. Instead the value reduces by 100 MB and the same memleaked behavior continues.

Memcaching has been limited to 32 out of which less than 1 MB is in use. So is there any accountability for the memory usage?

With hardware acceleration turned on I get weird artifacting on the Youtube timeline (see image), it looks like white noise in the real world since the image doesn't show all of them. Without the acceleration the artifacting disappears. Only noticed this on Youtube.
In rare cases it used to crash the display driver after switching videos, but I have not experienced this for some time now.
